mod_admin_shell, util.prosodyctl.shell: Process command-line args on server-side, with argparse support This allow a shell-command to provide a 'flags' field, which will automatically cause the parameters to be fed through argparse. The rationale is to make it easier for more complex commands to be invoked from the command line (`prosodyctl shell foo bar ...`). Until now they were limited to accepting a list of strings, and any complex argument processing was non-standard and awkward to implement.
